CRUSHER FOR ORE AND OTHER MATERIALS.

Specification of Letters Patent.

Patented July 21, 1908.

Application led September 16, ,1907. Seiial No. 393,040.

To all whom it may concern:

Be it known that I, HENRY EGGEEs, a citizenof the United States of America, residing in the city and county of Denver and State of Colorado, have invented a new and useful Crusher for Ore and other Materials, of which the following is a specification.

M invention relates to improvements in crus ers for ores,rrock, and other material, and the objects of my invention are: First, to provide an adjustable swinging jaw locking device for ore and rock crusher. Second, to provide a quick releasing device for the stationary aw supporting frames of ore and rock Crushers. And third, to provide an improved form of ore and rock crusher in which the stationary jaw and its supporting frame can be swung up over the top of the crushers frame, so that both the swinging jaw and the stationary jaw are in full view and can be cleaned, removed, and replaced by new ones, and in which the swinging jaw can be adjustably positioned relative to the stationary jaw, and can be instantly released from its adjusted locked position. I attain these objects bythe mechanism illustrated in the accompanying drawings, in which:

Figure 1, is a plan view of my improved Fig. 2, is a longitudinalsectional view of the same. Fig. 3, is an end elevation of the feed end of the crusher. Fig. 4, is a perspective view of the frame to the stationary jaw. Fig. 5, is a perspective view of the locking sleeve. Fig. 6, is a perspective view of a cross link, and in connection with the locking mechanism. And Fig. 7, is a side elevation on a reduced scale of the main frame of the crusher.

Similar letters of reference`refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1, designates the main frame of my crusher, which is preferably cast in one piece and comprises sides 2, which are connected at the rear by an end member 3, which is of less height than the sides, and a bed plate 4. Journal bearings 5, are formed in the upper ends of the side members, and a shaft 5A passes through these bearings, and extends eyond them far enough to receive a belt fly Wheel 6, which is secured on one end, and a crank handle wheel 7, which is secured on the other end. The central portion of this shaft is rovided with an eccentric portion 8, which extends along the shaft between the sides, and upon the eccentric portion of this shaft I hang a swinging jaw supporting frame 9, at its u per end. This frame hangs from this shaft own between the sides of the main frame to near the lower edge of the frame, at a slight rearward angle of inclination to the vertical plane of the axial center of the eccentric shaft, assuming the closed end of the frame to be its rear end. This swinging frame is provided at its lower end with a rearwardly projecting portion 10, in the end of which a transverse recess 11, is formed, which has a downward inclination from its open side. In the bottom of, this recess a pin 12 is seated, the ends of which eX- tend through slots 13, formed in the o posite sides of the frame, and to the ends of t 's pin I secure one end of a pair of tie bars 14, which are provided wit an eye ortion at their ends that fits loosely over tiie ends of the pin 12, in grooves formed in the pin close to its ends to receive theeye portion of the links. The oppositeends of these tie bars are threaded `and extend loosely through apertures formed in the ends of a cross link 15, which extends across the lower end portion of the feed side of the frame, and clamping nuts 16 are threaded to the ends of the tie bars and screw against the cross link, the nuts being provided with operating handles, as shown. The central ortion of this cross link is round, and upon 1t I mount an eccentric sleeve 17, which is lprovided with a recess 18, that extends along the sleeve from end to end, and into it to the axial center of the sleeve, the bottom of which is curved, as shown. This recess incloses the round portion of the cross link, and its curved bottom portion fits against the round surface of the bar, while the eccentric body of the sleeve ts rotatably in a semi-circular recess 19 formed in the adjacent-end of a frame 20, which supports the stationary crushing jaw, as will presently be shown. T'o this eccentric sleeve l secure one end of a hand grasping loop-shaped handle 21, the loop hand rasping portion of which projects upwardly from the eccentric sleeve and normally rests against the end of the frame 20. The inside face of the stationary frame 20, is formed to receive a steel ore or rock breaking jaw 22, and the stationary frame and the steel jaw are inwardly inclined from the top of the frame towards the lower end of the swinging jaw-supporting frame, but at a greater angle of inclination to a vertical plane than the swinging jaw frame, in order to form a wed sha ed space between the two that is wi er at t e top than at the bottom, and which is ada ted to receive the ore or rock to be crus ed. The frame 20 comprises an end member, and side members having journal bearings 20A through which the ends of the shaft 5A project, and su port the same. The sides of the frame, at tlieir lower ends, lie in recesses formed by the sides 2, of the main frame, and uprights 2A, which form an integral ,part of the sides 2, but are far enough away from the said sides to permit the side members of the frame 20 to lie between them and rest against the shoulder 2B, which connects the uprights 2A with the sides 2 of the main frame.

The front side of the swinging frame 9, is also provided with a removable steel ore or rock crushin jaw 23, which is removably secured to it in any suitable manner, preferabl by being formed with a beveled lower en which is engaged by a beveled lip at the bottom of the swinging frame, and by a bolt 24 at the to of the jaw and frame, that extend througii both jaw and frame and clamp the two together. A buHer device is also arranged. between the swinging frame and the rear end of the crusher frame. This buffer may consist of an suitable resilient device properly arrange to receive the resilient thrust of the jaw frame, but I preferably carry out this feature of m invention in the following manner: U on t e rear side of the swinging jaw frame, form a pair of lugs 25, between which I pivotally secure by a pin 26 one end of a buffer rod 27 the op nsite end of this rod rests loosely in an extends through an open slot 28 formed in the top of the rear end 3 of the crusher frame, which only extends u hi h enough between the sides of the crus er rame 'to form a support for this rod. The free end of this buffer rod is threaded, and a nut 29 is threaded to it. Washers 3() are also mounted on the rod on the inside of the nut, and between these washers, one of which rests a ainst the end of the frame, I mount on the ro a rubber spring sleeve 31, which is adjusted for tension by the nut, as the tightening of the nut against the rubber draws on the rod and lower end of the swinging arm, and which bears against the pin and causes it to pull on the tie rods and cross link, which presses the eccentric sleeve into its semi-circular bearing in the fixed end of the frame-20, which acts as an abutment; consequently the tightenin of the buffer rod nut holds the lower end o? the swinging arm under a pulling pressure on the tie rods, and eccentric sleeve, against its abutment, and thus holds the lower end of the swinging jaw frame in an adjustable iXed position against accidental horizontal movement from it relative tothe stationary jaw, but at the same time free to move in a rotary swinging lane towards and in operative ore and roc breaking relation to said fixed `aw. Removable wear plates 32, are placed between the sides of the frame 2O and the jaws to prevent the material that passes through the crusher from contacting with the frame 20. These wear plates have V-shaped edges, which fit in corres ondingly-sliaped recesses, in the sides 2, and in the end of the frame 20.

The operation of the crusher and of its adjustable swinging jaw and quick releasing lock, is as follows: The eccentric shaft may be rotated by a belt ap lied to the fly wheel pulley or by hand as desired, and as it rotates, its eccentric ortion imparts a rotary swinging and oscil ato movement .to the swin ing frame relative to the stationary jaw of 51e crusher. This oscillatory reciprocal movement of the swinging frame is much greater at its upper end than it is at the lower end, as the swingin frame is pivotally supported at its lower en on the pin 12, and the eccentric movement of the top of the swinging frame is consequently converted into a slight verticallyinclined oscillating or rocking movement of the lower end of the rock arm on the tie rods 14. The lower end of the swinging frame can be adjustably set at any desired position .relative to the stationary jaw, so as to regulate the size of crushed product by manipulating the tie rods 14, and buffer rod 27, and in case at any time it is desired to look at the crushin jaws, the eccentric sleeve is removed r'om the cross link 15 by grasping its loop handle and swinging it down in the direction of the arrow, which turns the eccentric portion of the sleeve out of its semi-circular bearing in the end of the frame 20, and allows the cross bar and tie rods to drop down below the end of the frame, when the said frame and its jaw can be swung up over the top of the main frame inthe direction of the arrow 33, with its jaw facing out, while the swinging frame and jaw 9, are exposed to full view from the forward end of the machine.

My invention is sim le, durable, and practical, and enables the jaws to be examined at any time without stopping the movement of the eccentric driving shaft and swinging frame.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

In an ore and rock crusher, the combination with the main frame, of the crusher frame, having a stationary jaw; an oscillating jaw arranged in operative relation to said stationary jaw, a recess in said swinging jaw, a pin journaled in said recess, a air of tie bars positioned one on each si e of said frame, provided with eyes at one end fitting and reciprocatory loosely over the opposite ends of said pin, and havin their op osite ends threaded, an abutment earing a jacent to said stationary jaw in said Crusher frame, a rotatable tie bars loosening and tightening eccentric abutment sleeve mounted in said abutment bearing, and provided with an open slot portion in its side, a link in said side slot extending across said frame, e e portions on the opposite ends of said lin fitting loosely over the threaded end portions of said tie rods, and a handled nut threaded to the threaded ends of each rod and arranged to screw against the
